Hydrophobic residues are greenish and yellow. Polar residues are blue, red, and inbetween.
Gly and Pro are black.
Helices are easily recognized, not only because they are indicated by the residue numbering on the top.
Nature is not going to put in polar residues to face the lipid. Those residues wouldn't serve
any purpose, and it would cost a lot of energy getting them there. These polar ones
point inward, probably facing each other in groups that work together on a functional task.
